Hello everybody,
sorry for my english, I am not native english speaker.

i cannot play my video. The frame is displayed, but the play button is gray and cannot be clicked. If the page gets loaded, the small playbutton is for a second white colored and change then in grey.

Google Chrome Browser
qigong-berlin.org/index.php/videotest

The Firefox Browser say that the format and MIME-Typ can not supported.

But I produced the video in the format mp4.

What am I doing wrong?

Best regards
Joerg

Sorry,
I checked a little bit the forum and find the problem.
I used the ".mp4" after the name of the video.
It works now without that perfect.
Best regards
Joerg
